Washington State's pure comparative rule means your traffic accident claim survives even if you carried significant fault. The payout decreases proportionally, so the police report's allocation of blame translates directly into dollars gained or lost.
How Pure Comparative Fault Works in Traffic Accident Cases
Pure comparative fault reduces your traffic accident damages by your percentage of blame but never eliminates your right to recover. If the evidence shows you were thirty percent at fault — perhaps for following too closely before the other driver ran a signal — your compensation drops by thirty percent. Even at eighty or ninety percent fault, you still collect a proportional share.
This system shifts the focus from a yes-or-no question to a precise percentage calculation. In traffic accident cases, police reports, camera footage, and citation records provide the raw material for that calculation. Each piece of evidence that moves your fault share down by even a few points directly increases your final payout.
Reducing Your Fault Percentage With Police and Camera Evidence
Because pure comparative fault converts every shift in blame into a direct change in your compensation, evidence gathering must be thorough from the first day. Document the scene — signal status, road markings, vehicle positions, debris — and request the police report as soon as it is available.
Your focus should be on eliminating or reducing any fault attributed to you. If the report notes that you were speeding or failed to signal, counter with camera footage or witness statements that tell a different story. Traffic-camera records, dash-cam video, and even cell-phone footage from bystanders can recalibrate the fault percentage. In pure comparative states, the effort of chasing down one more camera angle often pays for itself many times over.
A worked example with Washington’s rule applied
Take a traffic accident claim with documented losses like these:
| Medical bills | $11,700 |
| Lost wages | $9,600 |
| Other out-of-pocket costs | $2,400 |
| Pain and suffering (3.5× medical) | $40,950 |
| Gross value before fault | $64,650 |
Now apply Washington’s pure comparative rule. Say the insurer pins 30% of the fault on you: the claim is reduced by $19,395 to $45,255 — but it survives. Even a driver found 30% at fault still recovers the remaining share here, which is exactly why adjusters in pure-comparative states argue percentages rather than trying to kill the claim outright.
How Police Reports and Camera Evidence Shape the Fault Dispute
Two categories of evidence dominate traffic accident claims in Washington: the police report and any camera footage from the scene. The report captures the responding officer's assessment — who violated which traffic law, where the vehicles were positioned, and which driver the officer believes caused the collision. This document reaches the insurer early and frames the initial settlement offer.
Camera evidence either reinforces or undermines that frame. Intersection cameras, dash-cam recordings, and private security footage provide an objective timeline. A camera that captured the other driver entering the intersection on a red signal can turn a disputed-liability case into a clear one. Preserving this footage is time-sensitive — send written requests to every potential source within the first week after the collision.

Questions
Washington questions
If I was mostly at fault for a traffic accident in Washington, can I still recover damages?
Washington applies pure comparative fault, which allows recovery at any fault level. If your share of blame is seventy percent, you still collect thirty percent of the total damages. Police reports and camera footage are used to establish the exact percentage, and each point directly affects your payout.
How does the police report affect my fault percentage in a Washington traffic accident claim?
The police report provides the initial fault framework that the insurer works from. The officer's narrative, diagram, and any citations establish a preliminary allocation of blame. If the report contains inaccuracies, you can file a supplemental statement. Camera footage and witness testimony can further adjust the percentage during negotiations.
Does Washington's pure comparative fault rule apply to all traffic accident claims?
Pure comparative fault generally applies to all negligence-based traffic accident claims in Washington. It governs how damages are allocated when both drivers share blame. Government-entity claims may have separate procedural requirements including shorter notice deadlines, so check those timelines immediately if a public vehicle or road-maintenance issue was involved.
